OK so my PM inbox has been flooded with requests for free S4 coupons, and everyone who has requested one up until this point either has or will receive one. BITMAIN sent out TONS of coupons to everyone who has ever purchased a product from there. At this point, it's becoming a little time consuming to send out these coupons for free, so if you would like a coupon, I would like to request atleast a .005 BTC donation (currently less than $2 USD, a lot less than the $125 that the other guy was asking )to my BTC address for my time. Keep this in mind if you PM me from this point forward.

Keep working with MrGreenHat until he runs out, then hit me up!

I'll make the same offer; I have over 100 of these $400 off coupons, and I'd love for someone to put them to good use. I just bought 2 more S4s today, and I don't think I'll be buying any more for a little while.

PM me with your Bitmain user ID, and I'll provide you with a BTC address to send donations to.

Heh, Ill offer the same deal myself, or 10/0.02BTC. I imagine there are thousands of these coupons distributed in total.

Your HW Error is rather high.. and do you realise you have have a X on one of the chips?

Hard reset for that. I had one and a soft reset just makes it worse

Talking about that... my chain 1 goes offline after about 1-2 days running, sometimes in a matter of few hours. GUI will be reporting as if nothing wrong. You'll only notice when your hash rate at pool end drops. You can also look into the casing via the fans, you should be able to see 4 red leds if all chains are running. Was thinking of taking the S4 to a host but with me constantly having to look to see if there is 4 red leds, not going to be possible. Plus having to hard reset when you get "Hugs & Kisses".. makes it even more impossible to have the S4 hosted.

Hi everyone,i have got a strange problem with my Antminer S4 batch2, i listed founded problems:1-my S4's has different connections with FPGA controller, one of them is top left hash board connected to J7, other s4 same board is connected to J6. this is very strange or poor assembly.2-this J7 connector is going to the first hash board i think, but other hash boards red led is off except this J7 connected board led blink. 5 minutes waiting then this board getting hot and another five minutes all boards leds are on. then all of them is hot but THERE IS NO ETHERNET CONNECTION. 3-i worried power comp. and i changed 0720 to 0700 then i measured all hash boards voltages on 1500uF/2,5V capacitor.. wouuwww THERE WAS A PROBLEM! because we can never change 1 hash board's (j7 connected) voltage. this is allways 0750V. than i read confidential pdf of CSD95372B and TPS53641 this is i2c controlled buck converter and this is controlled by pic12f1822 on every hash board. So this 0,750 Volt i measured is over voltage protection limit. i am an electronic engineer by the way.
